Electro-Harmonix

This unique electronic music accessory is the product of extensive research into the characteristics of human speech. The advanced solid-state circuitry which has been designed around the data obtained employs critically tuned resonant filtering to create the continuous vowel series "A,E,I,O,U" depending on pedal position. Consonant sounds can be produced by percussive input such as guitar string plucking or damping. The result is a pedal and musical instrument controlled speech synthesizer housed in an extremely durable cast metal case.
